Why do communitarians think advertising can shape personal preferences?

Communitarians argue that personal preferences are not purely autonomous but are instead significantly shaped by the larger culture in which an individual is embedded. Because individual identity is socially constructed rather than existing in isolation, communitarians believe that cultural forces—including nonrational influences like commercial advertising—play a major role in forming what individuals desire and value.12

From this perspective, advertising does not merely reflect existing consumer needs; it actively influences the social context that informs an individual's identity and choices. Consequently, communitarians reject the libertarian view that any public effort to steer these preferences is inherently paternalistic or a violation of autonomy. Instead, they maintain that it is legitimate for public authorities to encourage individuals to resist harmful influences, such as those promoting smoking or obesity, as these interventions help protect the well-being of the community without undermining human dignity.1
